[MV-0001] "sitecoreEdgeContextId" is required.

I tried to make production release to Vercel with customized GraphQL Endpoint and I got this error: [MV-0001] "sitecoreEdgeContextId" is required. I got correct data from custom Edge, but then this Exception is raised.

I created custom GraphQL Endpoint with URL /sitecore/api/graph/edgePreview and this was deployed to Sitecore XM Cloud. This endpoint returns data of items in specific workflow states. I need to have non public site, which displays site without Draft workflow items. This works for local development, but not for production.

Environment variables looks like this:
SITECORE_API_KEY=XXX
GRAPH_QL_ENDPOINT=https://XXX.sitecorecloud.io/sitecore/api/graph/edgePreview
SITECORE_SITE_NAME=XXXX
DEFAULT_LANGUAGE=en
GRAPH_QL_SERVICE_RETRIES=3
FETCH_WITH=GraphQL

In previous versions it was not necessary to set SITECORE_EDGE_CONTEXT_ID for production. Is there any solution for this use case?

I was able to identify reason, why it works in dev environment.

headapps\XXX\src\Bootstrap.tsx
.....
if (process.env.NODE_ENV === 'development') {
console.debug('Browser Events SDK is not initialized in development environment');
}
.....
else {
CloudSdk({...})
}

If I modify this condition, I am able to connect to different Edge and application works.
